Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic cleaning technology, and in particular relates to an energy-saving and high-efficiency ultrasonic dust removal system for display screen panels. Background Technology

[0002] Ultrasonic cleaning devices for display panels are highly efficient cleaning equipment designed specifically for various types of display panels. Through high-frequency ultrasonic vibrations, they precisely remove dust, oil, residual photoresist, and other contaminants from the panel surface and crevices. Requiring no physical contact, they avoid scratches and electrostatic damage caused by traditional wiping methods. They offer advantages such as uniform cleaning, high efficiency, and compatibility with mass production line rhythms. Widely used in pre-cleaning, mid-process cleaning, and pre-inspection cleaning in display panel manufacturing, they are crucial equipment for ensuring the image quality and yield rate of display panels.

[0003] Chinese patent CN217314909U discloses an ultrasonic dust removal mechanism, including a dust removal head housing. An air outlet pipe and an air inlet pipe are respectively arranged on one side of the dust removal head housing, with two of each. An interface assembly is fixed to one end of each air outlet pipe and air inlet pipe. This device, by redistributing the positions of the air outlet and air inlet pipes, can avoid excessive airflow accumulation on both sides or in a certain section, reducing airflow fluctuation and improving the dust removal rate. By setting a guide plate, the high-pressure gas forms an uneven high-pressure chamber within the container while ensuring sufficient flow. This airflow is evenly guided into the amplifier through evenly distributed pressure relief holes on the guide plate. After re-pressurization and intensification, it produces a stronger and more stable acoustic airflow, maintaining a powerful output state for removing dust on the substrate and removing smaller and more stubborn dust particles. However, this device still has the following problems:
